Two locations of a fast-food restaurant, Location Q and Location W, were in a certain town with a large number of residents. A nutritionist investigated whether the proportion of orders that contained a salad was different at the two locations. The nutritionist obtained a random sample of orders from the Location Q restaurant and a random sample of orders from the Location W
restaurant. Of the 215 Location orders, 27 contained a salad; of the 175 Location Worders, 14 contained a salad. Let , represent the combined sample proportion, and let no and nw represent
the respective sample sizes for Locations Q and W. Have the conditions for inference for testing a difference in population proportions been met?
